1S 3.7V 3A 2MOS BMS Li-ion 18650 Battery Protection Board
Description:
1S 3.7V 3A BMS (Battery Management System) Protection Board is a compact and reliable safety module designed for single-cell 3.7V Li-ion or LiPo batteries, such as 18650 cells. This BMS features a 2MOS (dual MOSFET) configuration to provide essential protections, including overcharge, over-discharge, and short-circuit protection, ensuring the battery operates safely and efficiently.
This module is especially useful in DIY power banks, battery packs, wearable electronics, flashlights, and other portable devices where safe charging and discharging of lithium cells is required.
Features:
Single-Cell (1S) Protection
1. Overcharge Protection
2. Over-Discharge Protection
3. Overcurrent & Short-Circuit Protection
4. Auto-Recovery
5. 2-MOSFET Design
6. Compact Size
7. Rated for 3A Current
8. RoHS Compliant
